Abstract: According to an embodiment of the present invention, a variable valve lift device comprises: a valve arranged to open and close a port; a lever arranged to drive the valve to a high lift or a low lift; and a fluid pressure gap adjusting part for supporting a lower part of a leading end of the lever. The lever includes: a first lever corresponding to a high cam of a cam shaft; a second lever, corresponding to a low cam of the cam shaft, and connected to the first lever through a hinge arranged in a rear end, and having a piston groove in a front end; a piston which is inserted into an inside of the piston groove; a piston elasticity member for elastic supporting the piston toward an inside of the piston groove; and a fluid pressure supplying part for making the first lever to press the second lever through the piston since the front end of the piston protrudes to an outside of the second lever. An oil jet for relieving a fluid pressure, which is formed between the piston groove and the piston, toward an outside is formed at a constant interval toward a movement direction of the piston. Therefore, the valve can be controlled rapidly and variably since a fluid pressure loss is reduced in case the fluid pressure is supplied, and a fluid pressure is discharged rapidly to an outside in case the fluid pressure is relieved by forming a first and a second oil jet in a piston groove at a constant interval toward a movement direction of a piston.
